Question: Retention Test Scores. A sample of non-English majors at a selected college was used in a study to see if the student retained more from reading a 19^th century novel or watching it in DVD form. Each student was assigned one novel to read and a different one to watch, and then they were given a \(20\) point written quiz on each novel. The test results are shown below At a = 0.05, can it be concluded that the book scores are higher than the DVD scores?

Book 90 80 90 75 80 90 84

DVD 85 72 80 80 70 75 80
